So the portion of the estate left to you is 40K (a third of the 120K) plus 45K (a quarter of the 180K). Thus an inheritance of €85 K
Your tax will be 33% of (85+9-32.5) which is roughly 20K. So once you get the inheritance into your bank declare it to revenue, along with your 9K previous inheritance, and pay them the €20K tax bill.
If you want the inheritance - about €65k for you then you pay the tax, your only other options is to decline the inheritance or decline it in favour of one of the other beneficiaries.
You seem to be focused on the house but that is not part of your inheritance and the nephew who inherited that will have to deal with it, not you.
